Answer to Question #155360 in Inorganic Chemistry for Alma

Question

Calculate the Qsp for the mixing of 30.0mL of 3.7 × 10^-3 M Sr(NO3)2 and 25.0mL of 0.02 M Na2SO4

Answer 1

Qsp of SrSO4 =

Concentration of Sr²⁺ × Concentration of SO₄^2- .

= ( 30 × 3.7 × 10^-6 ) / 55 × 10^-3

×

( 25 × 0.02 × 10^-6 ) / 55 × 10^-3 ).

= 30 × 3.7 × 25 × 0.02 × 10^-6/ 55 × 55

= 1.8 × 10^{-8 .}.
